Jenn-Air Refrigerator RS Error: Temp Sensor Malfunction
What Does Jenn-Air Refrigerator Error Code RS Mean? The RS error code on Jenn-Air refrigerators indicates the refrigerator compartment temperature sensor (thermistor) is malfunctioning. This sensor tells the control board the current temperature — when it fails, the board cannot regulate cooling properly. Common Causes Failed thermistor: The temperature sensor has drifted out of calibration […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. The refrigerator may still cool but cannot maintain accurate temperatures. Use a standalone thermometer to monitor food safety until repaired.
Can I reset the code?
No. A failed thermistor requires physical replacement — the error will return after any reset.
When to stop immediately?
Stop if you notice: Food freezes in the fresh food section, Temperatures remain above 40°F.
Symptoms You May Notice
Fresh food section too warm or too cold
Temperature swings between extremes — items may freeze or spoil because the compressor runs erratically.
Displayed temperature does not match actual
The panel shows one temperature but a thermometer inside reads significantly different.
Compressor runs continuously
Without accurate temperature data, the board keeps the compressor on indefinitely trying to reach the set point.
Possible Causes
Failed thermistor
The temperature sensor has drifted out of calibration or failed entirely, providing inaccurate readings.
Requires ProfessionalDamaged sensor wiring
The wire from the sensor to the main board is broken or has a corroded connection.
Requires ProfessionalSafe Checks You Can Do
-
1
Compare displayed vs actual temperature
Place a glass of water with a kitchen thermometer in the fridge for 2 hours. Compare the thermometer reading to the display.
A difference of more than 5°F confirms the sensor is reading incorrectly.
-
2
Power cycle and monitor
Unplug for 5 minutes. After restart, watch if the displayed temperature tracks toward the actual temperature over a few hours.
If the display reads extreme values (like -20°F or 70°F), the sensor has likely failed entirely.
When to Call a Professional
Contact a qualified technician if:
- Thermistor resistance far from specification at room temperature
- Sensor connector shows corrosion or damage
- Replacing the sensor normalizes temperature control
